Floridan Flamingo 

When one person (high on meth), sticks there head in another person (also high on meth)'s asshole. the meth may be substituted for crack as crackhead strength can help with the "jamming"

Mark, "the other night I got Fucked up and gave Miles a Floridan Flamingo!"
Dave, "Dude, get help."
